What is the optimal size of a project team, above which
additional members do not contribute productivity equivalent
to the percentage increase in the staff size?
The answer is 3.
Since the number of communication channels in an n person
team is n(n-1)/2, we get the following communication
channels for the given size of the team:
3 people = 3 channels
5 people = 10 channels
7 people = 21 channels
9 people = 36 channels
11 people = 55 channels
As you can see, above a team size of 3, people have to
communicate a lot more thus reducing their productivity.
So, three is the optimal number.
For optimal size of a project team..
the % increase in staff size should be “Zero”
reason:
additional member directly proportional to increase in
staff size..
